Brian Brazil	9b382647b5	Remove optional vector() 2nd argument	9 years ago
Brian Brazil	69f5fa0c1e	promql: Add vector function. ... Currently the only way to convert a scalar to a vector is to use absent(), which isn't very clean. This adds a vector() function that's the inverse of scalar() and lets your optionally set labels. Example usage would be vector(time() % 86400) < 3600 to filter to only the first hour of the day.	9 years ago

Brian Brazil	29e8dc2c49	promql: Add 'bool' modifier to comparison functions ... When doing comparison operations on vectors, filtering sometimes gets in the way and you have to go to a fair bit of effort to workaround it in order to always return a result. The 'bool' modifier instead of filtering returns 0/1 depending on the result of the compairson. This is also a prerequisite to removing plain scalar/scalar comparisons, as it maintains the current behaviour under a new syntax.	9 years ago
Julius Volz	61c42c8da0	Change relabel_replace() to do full-string matches. ... THIS IS A BREAKING CHANGE. Fixes part of https://github.com/prometheus/prometheus/issues/996	9 years ago
Julius Volz	27ed874358	Implement label_replace() ... Implements part of https://github.com/prometheus/prometheus/issues/959.	9 years ago
Brian Brazil	d6a80c2b76	promql: Add support for predict_linear(my_timeseries[1h], 7200) ... This will give a prediction for the value of my_timeseries in 2 hours, based on the last hour of data.	9 years ago
Fabian Reinartz	94cd321be1	promql: error if all label matchers are empty.	10 years ago
Julius Volz	5e2d1c1464	Deprecate `keeping_extra`, rename it to `keep_common`. ... `keep_common` is more in line with the function name `drop_common_labels()` terminology-wise, and also more in line with `group_left`/`group_right` (no `...ing` verb suffix). We could also go the full way and call it `keep_common_labels`. That would have the benefit of being even more consistent with the function `drop_common_labels()` and would be more explanatory, but it also seems quite long.	10 years ago
Brian Brazil	f34de493d5	Add increase() function, to replace delta(..., 1). ... This calculates how much a counter increases over a given period of time, which is the area under the curve of it's rate. increase(x[5m]) is equivilent to rate(x[5m]) * 300.	10 years ago
Julius Volz	d44a89c6e8	Implement changes() function. ... changes() takes a range vector and returns the number of times a value has changed in the given time window for each time series as an instant vector.	10 years ago
Julius Volz	6f33ed9e59	Add resets() function to count counter resets. ... resets() returns for every range vector element how many counter resets there have been in the specified range.	10 years ago
